Silent Auto-Track

Silent Auto-Track is the mode every new group starts in. It exists for busy trading chats where contracts fly past every few seconds and a preview card on each paste would drown the conversation. The bot watches silently, captures every valid contract address, expires the entries on a TTL, and rotates them out FIFO when the list fills.

What it does

When Silent Auto-Track is on, pasting a contract address in the group triggers exactly nothing visible. No preview card, no confirmation, no reaction. Behind the scenes Prysm validates the address, resolves the chain, and appends the token to the group’s auto-track watchlist with an expiry timestamp.

You see the result when somebody runs /list (or /compact) — every recently-pasted contract is already there, sorted, priced, and ready.

The original message is left alone. Other bots in the chat that also react to pastes still see it; Prysm just doesn’t add to the noise.

Note

The bot still has to actually receive group messages for any of this to work. Telegram’s privacy mode blocks regular messages by default — see the privacy-mode caveat below.

The four knobs

Four group settings shape the behaviour. Three are tunable from /settings; the fourth (list size) is set by the bot owner.

Knob	Default	What it does
Status	On	Toggles the whole feature for the group. Off = Manual Mode.
Period (TTL)	1 day	How long each auto-tracked token lives before it expires.
Min Pastes	1×	How many times a contract must be pasted within the TTL window before it qualifies.
List size	10 tokens	Maximum auto-tracked tokens at once. FIFO when full.

A token only enters the list once its paste count reaches Min Pastes within the active TTL window. With the default of 1× every paste is captured immediately. Raise it to 3× and a contract has to appear three times before Prysm tracks it — useful for filtering out one-off mentions in noisy chats.

The expiry clock starts the moment the token enters the list, not the last time it was pasted. After the TTL, a background sweep (running every five minutes) deletes expired rows.

FIFO eviction

When the list reaches the size limit and a new contract qualifies for tracking, the oldest token in the same forum topic is dropped to make room. Within a regular (non-forum) group this is just “oldest overall”; in a forum group with multiple topics, eviction is scoped to the same topic the new paste came from.

The size cap itself is counted across the whole group. So a forum group with the default cap of 10 has 10 slots total, shared between every topic.

What gets ignored

A few flows behave differently while Silent Auto-Track is on:

• /add is silently dropped in the group. The default mental model is “every paste is already captured, you don’t need to type anything.” If you genuinely want to add a token by command, switch the group to Manual Mode first.
• /track is silently dropped for the same reason.
• Multi-paste messages (more than one contract in a single message, separated by newlines or commas) fall back to the regular preview flow — Prysm shows a card with an explicit Add button. Bulk pastes are intentional enough that the silent shortcut would surprise more than it would help.

Single-line pastes are the only path that goes silent.

Tuning the knobs

The group’s tracking settings live behind /settings → Tracking → Silent Auto-Track. Only group admins can change them.

1. Run /settings in the group.

2. Tap 🔍 Tracking.

3. Tap 🔇 Silent Auto-Track. The submenu shows the current status, period, min-paste count, and how many slots are filled.

4. Tap a button to change a setting:

   • ✅ Enabled / ❌ Disabled — toggles the whole feature.
   • ⏱️ Period: 1 day — picks 1h, 6h, 12h, 1d, 3d, or 7d.
   • 🔢 Min Pastes: 1× — picks 1×, 2×, 3×, 5×, or 10×.
   • 🗑️ Clear All — wipes every auto-tracked token in one go (useful for resetting after a noisy session).

The list size doesn’t appear here as a knob. The default cap is 10 and is set by the bot owner; if you genuinely run a chat that needs more, ask them.

Switching off and on

Three ways to flip the mode:

• The welcome-message button. When Prysm joins a new group it posts a welcome card with a 🔍 Switch to Manual Mode button. One tap.
• /settings. The submenu above. Tap the status row to toggle.
• /autodetect. This command toggles the separate auto-detect setting — whether Prysm reacts to pasted contracts at all. With auto-detect off, neither Silent Auto-Track nor Manual Mode runs; pastes are ignored entirely. It’s the quietest possible setting and is mostly useful when you only want the bot to respond to slash commands.

The two settings stack: Silent Auto-Track only takes effect when auto-detect is on. Switching to Manual Mode keeps auto-detect on but tells the bot to show preview cards instead of capturing silently.

A few things specific to Silent Auto-Track mode:

• The percentage is always 1h regardless of the group’s price-change period setting. Auto-tracked rows are short-lived and a 24h baseline rarely lines up with their actual time on the list.
• The Add Token button under /list is hidden — adding tokens by hand isn’t the workflow here, pasting is.
• Rows that have crossed their TTL are gone before the next render. There’s no expiry countdown shown per row; tokens just disappear.

Privacy-mode caveat

Silent Auto-Track lives or dies by whether the bot can see your group messages. Telegram’s privacy mode hides regular (non-command) messages from bots by default — and a contract address pasted on its own is a regular message. Until you fix this, the silent capture has nothing to capture.

Two ways to unblock it (you only need one):

• Promote Prysm to admin in the group. Admin bots see every message regardless of privacy mode.
• Disable privacy mode in BotFather for the bot itself.

The welcome message’s “Add me as admin to enable contract detection!” line points at the same thing.
